So Just want to see some thoughts of users here,
Currently just picked up a Turbo Tweak Tune 93 Street 19/17 15-17 psi. Eric stated his tune the maf needs to lock onto 255 to have proper fueling.
Car has usual mods, TA-49, Exhaust, K&N Intake, FPR, Racetronix 255 Pump and some other parts not as important
The boost is set to about 15 psi and the Maf reading reads 220- 236 during the pull and it seems like the Maf readings take forever to come up like 236 is max WOT high rpm during this pass I see super Lean O2 values like 710-735. I also believe the ramp up is super lean too, backfired on me once at like 2psi, 5KR and I think low o2 values (I'm thinking cause lean but I was more worried about lifting than looking at the o2 values)
When I added 15% more fuel values jumped up to like 740-760 o2 and I don't see any KR but still feels like its running super lean and seems to fall lean on the spool up still.
Eric stated to me that the tune wont run right if the MAF isnt locking onto 255, Which it currently isn't so I'm thinking the Maf is kind of lazy and low on the calibration. To remedy this problem, should I just get a maf translator with a LT1 3" maf ? Slightly bump up the WOT setting on the translator if the LT1 sensor isn't hitting 255 so it hits 255 every time.
Idle Values
These are my numbers at Idle after a 20 minute drive.
AF -04
L8 - 30-31
Bat -13.7
INT - 128
BL - 135
CLE -166-170
ATS - 131 (I know its hot was idling for a few minutes sitting while I was writing down numbers)
R - 800
TPS - .38 WOT Verified to be Locked to 4.70 (Caspers TPS throttle enhancer)
Iac - 15
Car worked just fine on my (96) octane PTE tune 20 degrees timing at 18-19 psi, O2 values 800-815 so I am assuming this chip is locking to 255 cause it should be wayy past locking out the maf.
Any thoughts on the future and how I can get MAF readings to lock to 255 on 15-16 psi ? Maf Translator & LT1 maf?
